Sender SOAP Adapter: zipped Payload or zipped Attachement possible?

[Former Member]

Hi,

I've a SOAP --> PI --> Proxy Scenario. As the payload of the message can become quite huge (around 10MB), I'd like to zip the message.

From the documentation it's not clear for me if the Sender SOAP Adapter can be enhanced with the standard PayloadZipBean:

"You cannot add your own modules to this adapter" --> so is it possible to use modules provided by SAP?

If it's not possible: is there another way to send the message zipped via SOAP, e.g. as a additional attachement to the SOAP message, and to unzip the attachement / use the content of it as message payload for mapping?

Please note: usage of SOAP is a must for that scenario.

Best regards

Holger

it can be possible. Simply read the zipped attachment in mapping (Java Mapping) then unzip and transform (map) to the target structure.

Hi all,

thanks for your answers. File size is a question due to limited network speed between sender and PI. If I can reduce the data package to be transferred, it'd be a big help. Therefore I'd like to zip the message.

Okay, so it's not possible to enhance the SOAP adapter with modules. The Java mapping: how should it work? How can I unzip the data? Where is the zip file in my Webservice (in the body as binary or in the attachement)?

Best regards

Holger

Dear Holger,

1. SOAP adapter doesnot allow modules

however instead of java mapping i would suggest convincing the sender to send small chuncks of messages

You may use soap adapter with axis framework. It would then allow you to add modules.

Dear Prateek,

can you throw some more light on how to use SOAP adapter with AXIS

In this case it would be sufficient to use Content-Encoding gzip.

This is part of the HTTP protocol and will be unzipped automatically by the HTTP framework, so you need not do anything special in SOAP adapter.

See http://tools.ietf.org/html/rfc2616#section-14.11

Check if your SOAP client is able to use that.

i do not think that you need to reduce the size of your message...SOAP message are already in XML format..

and trust me ..10 MB should not create any problem

Hi Holger,

You cannot use modules in the SOAP sender adapter, so it is not an option to use the PayloadSwapBean.
